Brians heads will beat the ootb ede's for power pretty easily for roughly the same money as the ede's before correction. More than make up for any weight penalty. Budget sounds like a concern here.

My Dart went 7.42 in the 1/8 at #3240 with my stock stroke 340 and 4.30 gears shifting at 6400. It only picked .006 over the 3.91 set I had in it before. My Edelbrocks were ported by Curtis Boggs, it had a Hughes 3742 flat hydraulic cam, 11.2-1 compression and a Weaind X-Celerator single plane intake with a Quick Fuel Q-750 on it. According to the online calculators it made in the 450 hp range  . I drove it a lot and once I installed a mechanical fan and shroud it never had any overheating issues, plus it ran on pump 93. Personally I like all the benifits that go along with the aluminum heads  . I now have a 408 and it's a bear but also a lot more $$$ than I had in the 340.

stock replacement heads are fine if you dont have any intentions making big power in the future.
 It's actually cheaper to buy a head that has more future potential to it than to settle for something less because right now you only want X amount of power. All of you should know that once you have X amount you'll want more later so if you buy a head that has future potential you are bucks ahead.

Would you prefer W2 to the Eddys? I cannot see that Eddys are limiting when you "screw" them?

What do you think of this stroker kit?

That's a 4.070 bore kit so you need an R block or a 340 block. Also is that a forged crank? If not I'd pass. Get a forged crank to start with and you won't have to buy another one later.

Scat I beams are decent rod for the money though. But those dont look like scat i beams in the picture.

yes i sure would prefer them,they are known to make very good power if done right:) the screw was sort of a bandaid to make up for the limitations of the heads, and W-2īs would have taken me much further before i would find the need for that screw.

Thanks again, and I'll be looking to pick a lot of these parts at the Carlisle show next week. I still think the hardest decision is to which head to buy.

Test an OOTB ede, not a corrected head with a better valve job, against Brian's RHS head and get back to us.
This guy is on a budget from his statements.

Sure flow vise maybe but there are other benefits with ebrocks.
I have had ootb ebrocks and they have worked for me, needed no work.
I run rhs on my 408 now and im not very happy with them, they flow good but i needed to enlargEn the holes for one valvecover and for the headers and the intake fits like crap
I'm talking about Brian's heads, pull them out, slap them on and POWER produced compared to the OOTB ede's, not fit issues. What other suppliers heads do, not even a consideration, I was specific about the supplier. Not to mention component quality, springs, retainers, which gets lost in the shuffle in these deals.
If you have a pair of Brian's heads on your 408, swap those OOTB ede's on, then you'll be real disappointed in how it runs.
I did a bunch of clearancing on my ede's for pushrods. The crane roller rockers sure didn't fit with out clearancing either, so springs/retainers got swapped out. Just about every SB edelbrock air gap intake needs to be cut to fit stuff anymore. Fitting stuff up is just part of the game. Nothing is without warts. There are things about the rhs head that I'm not fond of too, none of my concerns about that are important when comparing to ede's.
Weight, 40 pounds... REALLY? This is the ONLY place the OOTB ede has an advantage for the OP's engine. How much HP does it take to overcome 40#? Like mentioned, I'll take the less expensive HP produced by the IMM RHS head over the 6-800 dollars in additional porting required on the ede's to get them in the same ball park. Most cars, especially street/strip cars, don't work well enough from a chassis standpoint to notice the weight difference. Maybe go on a diet to help out. 
I've never had a problem bolting up headers to the RHS X heads, tti, hookers (comp and SC), dougs, hedmans. I've never had to clearance a valve cover for a bolt hole either.
This post by the OP has BUDGET written all over it. Figure your all in price on both, especially a 450-500 hp engine which doesn't require anything fancy. You could get there with a set of J heads too...
Pick your parts, pay your money!

I'm also building a (relatively) low buck 340. Have already the basic parts except the cam and the pistons. I intend to keep it simple, flat top pistons and either a solid flat tappet or roller cam with a single E85 carb. The heads are brand new (NOS?)closed chamber W2's bought from moparts forum that I will try to port, the crank is a stock 340 unit and the rods H-profile steelies. Mahle offers pistons, they have coatings & rings included and from what I've seen are good quality, light list pistons. They should provide CR between 11.5 -12_1 depending of the gaq between the head and block. Haven't thought much about the cam yet since still in early stages, the car will weigh around 2600 lbs with driver and the rest of the drivetrain is a doug nash maual and 8 3/4 with ladder bars.
